Synopsis
========
Multiple vulnerabilities in tcpdump could result in execution of
arbitrary code or Denial of Service.

Background
==========
tcpdump is a tool for capturing and inspecting network traffic.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/tcpdump < 4.6.2-r1 >= 4.6.2-r1

Description
===========
Multiple vulnerabilities have been discovered in tcpdump:

* The olsr_print function function contains an integer underflow error
(CVE-2014-8767)
* The geonet_print function function contains multiple integer
underflow errors (CVE-2014-8768)
* The decoder for the Ad hoc On-Demand Distance Vector protocol
contains an out-of-bounds memory access error (CVE-2014-8769)
* The ppp_hdlc function contains a buffer overflow error
(CVE-2014-9140)

Impact
======
A remote attacker may be able to send a specially crafted packet,
possibly resulting in execution of arbitrary code or a Denial of
Service condition.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All tcpdump users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-4.6.2-r1"
